Which function has a vertex at the origin?
o f(x) = (x + 4)
o f(x) = x(x – 4)
o f(x) = (x – 4)(x + 4)
o f(x) = 2

B)

Step-by-step explanation:

To find the function which has vertex at the origin.

Solution:

For a function to have its vertex at origin the function must pass through point (0,0) which means .

We will find for each of the given functions and check if it has vertex at origin.

To find we will plugin in the function.

A)

Vertex is  not at the origin.

B)

 [Any number times zero is = zero]

Vertex is at the origin.

C)

Vertex is  not at the origin.

D)

Vertex is  not at the origin.
